Aflatoxins in Imported Peanut Meals

The aflatoxin contamination and the mycoflora of eighteen imported peanut meal samples (Indonesia, U.S.A., Brazil, India) were examined.Aflatoxins were detected in all of peanut meal samples except two from U.S.A. The most strongly aflatoxin-contaminated sample showed more than 1000ppb of aflatoxin B1.By examining the mycoflora of peanut meals, Aspergillus flavus and Asp. parasiticus, the species having productivity of aflatoxins, were detected from fifteen samples. All strains of Asp. parasiticus and about half numbers of strains of Asp. flavus isolated from peanut meal samples showed productivity of aflatoxins.
